Colts coach Chuck Pagano was diagnosed with leukemia last week and will likely miss the majority of the season fighting the disease. But he's far from forgotten in Indianapolis (and around the NFL), with the Colts firing up the CHUCKSTRONG campaign to honor and support Pagano.

At the team's website, the Colts are selling t-shirts, posters, wristbands and other items, with proceeds from those going to help fight leukemia. #CHUCKSTRONG is blowing up on Twitter, and the team will use Sunday's game as a way to recognize the missing coach.

A #CHUCKSTRONG banner (above) is hanging at one end of the stadium, and players are obviously on board as well. Colts quarterback Andrew Luck was rocking a CHUCKSTRONG shirt in a picture the Colts posted on Twitter.

"Best care in the world," Pagano wrote. "These people do so much for so many. Most selfless people I know. Thanks to all at IUH!!"

Pagano also sent an email to Colts players, per Ian Rapoport of the NFL Network, providing them with an inspirational message about staying positive and overcoming.

"My condition will not determine my position." Pagano wrote. "I understand the condition but choose to focus on my position," Pagano wrote to the players. "That is to stay positive and SERVE. WE WILL, WE CAN, WE MUST. WE HAVE NO CHOICE. BY ANY MEANS NECESSARY. WE WILL OVERCOME. IT'S ALL IN PROPER STATE OF MIND."
